Evaluating Two Variable Expressions

In this video, Mr. J explains how to evaluate expressions with two variables using four examples. The video covers the process of substituting values for variables and applying the order of operations to solve expressions. Examples include simple addition, division with parentheses, multiplication with exponents, and a combination of operations. The video aims to help viewers understand how to systematically evaluate expressions by plugging in values and following the correct order of operations.
